5.2 External antenna voltage
The Jupiter 31 provides DC power to the external active antenna through the antenna power
input pad (VANT). The DC supply in the coax cable is vulnerable to over current if a fault occurs
in the antenna or if the antenna cable gets damaged.
Typical values for the external antenna are shown in Table 5-1.
5.3 External I/O connector
The OEM communications interface is a dual row, straight 2 x 10-pin field connector header (J1).
The pins are spaced on 2.0 mm centres and the pin lengths are 7.0 mm off the board surface
with 1.3 mm at the base for plastic form. Figure 5-1 shows the 20-pin I/O connector. The mating
female connector is an IDC receptacle.
